A short update on my Raspberry Pi security alarm project

Hello again — it seems to be close to a year since I last managed to get some words published on this blog. And almost three years since I last wrote about my Raspberry Pi security alarm project 😮

But the project is still alive and well. We use it every night and whenever we are away, and it just works 😃 Development usually happens in bulk, with very little happening in between.

Since the last post, the system has progressed a lot:

There are so many things to explain that I don’t know where to start… That is probably the main reason I find it hard to document this project — where do I begin?

Writing long, detailed blog posts is extremely time consuming — and finding that time is hard. So my plan is to write shorter posts, tackling one topic at a time.

Here are some topics that I am planning to cover in future blog posts:

• New Zigbee keypads
• What does the Arduino microcontroller do?
• Replaced Aqara with Hue Zigbee motion sensors
• The electronics; inputs, outputs, and schematics
• Water alarm implementation
• Battery, power, and charging
• Thinking about fire alarms
• CLI and scheduled tests

This is just the first post in my attempt to break the writer’s block.

🖖
